BASS RIVER TOWNSHIP, N.J. (CBSNewYork) — Some people on their way back to New York City from Atlantic City on a Greyhound bus Sunday afternoon got a little bit of a scare.

Not long after the bus turned onto the Garden State Parkway, witnesses said a woman became agitated and began threatening to shoot everyone onboard.

One of the people on the bus was 1010 WINS’ Brian Carey.

“A woman on the bus started threatening passengers, saying that she’s bipolar, and that she’s going to kill somebody, so we went up and told the bus driver,” Carey said. “The bus driver pulled over to the side of the road.”

The woman got upset and made the threats when two women were taking pictures of each other, and she thought the women were photographing her.

But the woman had been acting strangely before she threatening everyone on the bus, witnesses said.

“When I first came on the bus, she was sitting in the aisle seat in the back around the window, and there were not many people, so I asked if I could sit with her, and she just stared at me for like a minute,” said passenger Jenna Silver.

Silver said she was later subjected to a personal threat from the woman.

“I was on my phone texting, and she said, ‘What are you doing over there? Are you texting the police? Are you telling the police about me? You better not be telling the police about me. You what to know what I have in my bag? You want to know a secret?’” Silver said. “And she starts putting her hand in her bag, and, like, looking at me, and saying, ‘You want to know what’s in my bag? I don’t think you want to know what’s in my bag.’”

The woman did not display a gun at any point, and police said she didn’t really have one.

The bus driver did not pull over right away, witnesses said. But once he did, Bass River Township police were called, and the woman was arrested.

Witnesses said everyone was screaming by the time the driver actually pulled over.

Passenger Jennifer Hoffman was shocked that the woman was ever let on the bus in the first place.

“Apparently, this woman was causing a lot of trouble at the gate, so I don’t know why she ever would have been permitted to have been on the bus,” Hoffman said. “There’s no metal detectors, there’s no any type of screening for passengers to get a bus ticket.”

It was not clear if the woman was charged with a crime. Police said she was taken for a psychological evaluation.
